This is a very short workout. Of course, it is labeled as 20 minutes, so this is no surprise, but it's really only 17 1/2 minutes of running (and that is if you turn your treadmill on before Grace tells you to.) I did warm-up a little before I started and kept going a bit after she said to stop, so I could get 2 miles in (I'm not very fast!) That is about the minimum I would ever want to run, so I can make this workout useful with those little changes.

I do like having the option for a really quick and fast run, so I enjoy these 20 minute workouts. I am able to run faster than I can when I do the longer workouts, which probably makes me like them even more.

The music in this is not quite as good as set 1, I thought, and I've heard most of it in other iTreads, but I liked it overall.
